" Mauve/1 Patented Mar. 14, 1939 UNITED STATES- PATENT OFFICE METHOD OF ERECTING CONCRETE STRUCTURES 2 Claims.

This invention relates to the method of and means for erecting concrete structures, and an object of the invention to provide novel means in the nature of molds to hold the concrete or plastic composition until the same is set and becomes self-supporting.

It is furthermore an object of the invention to provide a mold having novel means for holding reinforcing bars, around which the plastic composition is forced by tamping or otherwise, the said bars also preferably projecting from the mold to act as anchorages for adjacent parts of the structure.

It is a further object to provide sectional members coacting with the main mold or form which will permit the erection of columns in succeeding sections after a previous section has hardened or set.

It is furthermore an object of the invention to provide novel forms for holding concrete to form sidings or internal walls which may be associated with the columns formed as aforesaid.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which:

Figure 1 illustrates a view in perspective of a column form, with parts associated therewith;

Figure 2 illustrates a perspective view of a column having the reinforcing rods and the parts associated therewith for forming an internal or external wall which is anchored to the column;

Figure 3 illustrates a sectional view of a column With the forms assembled preparatory to their being removed after the column is formed; and

Figure 4. illustrates a sectional view of a plurality of columns and parts associated therewith;

Figure 5 illustrates a modified form of retaining plates for the wall; and

Figure 6 illustrates a modified structure for molding columns.

In carrying the invention into practice, the column form 5 may be of a length suitable for the formation of a column of appropriate height or length, and the form is preferably in the nature of a channel iron and it may be formed of sheet metal or other appropriate material. The flanges 6 and 1 have coinciding recesses or slots 8 which are intended to form seats for reinforcing rods or bars 9, as shown in Fig. 1. In

the formation of a column or the so-called pouring of the plastic composition, a coacting retaining form I0 is employed, which is likewise a channel member, and its flanges preferably fit inside of the flanges 6 and I and the edges of the flanges preferably engage the reinforcing bars held by the main form. In Fig. 1, a lower portion A of the column has been molded and the retaining form. 10 has been moved to an elevation for the purpose of pouring the second section of the column or post and, of course, when the secondsection is set, the form will again be moved with relation to the main form. The reinforcing rods are engaged by the flanges of the movable channel member and limit the inward movement of said movable channel member so that the size of the column is uniform, and furthermore, said rods act as guides for the movable channel member as it is elevated to a position to pour the succeeding section of the column.

The flanges 6 and 1 are preferably flared toward their outer edges, as shown in Fig. 3, to permit the assembly of the retaining form therewith and its removal after the composition is set, so that by the use of these two members associated with the reinforcing rods, a column is built in sections progressively from one end to the other.

After the column is constructed with the reinforcing rods projecting therefrom, the walls of the building are poured and preferably sheets of tarred paper or other insulation II are applied to the space between the columns and overlap said columns to the degree preferably where the edges of the insulation engage the reinforcing rods, as shown in Fig. 2.

The forms for retaining the composition while it is setting comprise a plurality of plates l2, each having an inwardly extending flange I3 and an outwardly extending flange I4 and when these are assembled in spaced relation to the insulation, they rest one on the other edgewise and are held in place by rods or posts l5, which latter are tied in place by extensions of the reinforcing rods or by retaining devices l6 extending from the said reinforcing rods. Only a few of the ties or retaining devices are necessary for each of the posts, as the only requirement is that they shall be held so that the plates may be retained in place during the pouring of the composition.

In Fig. 2, a lower section B of the wall is shown and the outer surface is stepped to simulate a clapboard construction and the plates are set to receive the plastic composition for the second section.

The inner wall I1 is preferably reinforced by' the rods, as shown in Fig. 4, and the insulation I I is'arranged on the inner surface thereof. Figure 4 shows a plurality of posts or columns and the formation, the plates l8 will have outwardly extending flanges IS on both edges and when they are assembled as shown'in Fig. 5, the flange of one plate will rest on the flange of the lower plate and thus a. straight surface will be imparted to the wall.

In order that the matter. will be further understood, the inner wall shown in Fig. 4 may be a plaster finish or other plastic composition.

In Fig. 6, a form is illustrated for molding a round column and obviously, these forms may be otherwise shaped. The main molding section 20 is curved, as shown, and the coacting retaining plate 2| has its edges fitting within the main mold section preferably in contact with the reinforcing bars in the same manner as is done in assembling the mold sections of Fig. 1.

The movable section of the mold may be held in its different positions of adjustment by clamps of conventional form.

I claim: 1

1. The herein described method of forming a structure consisting in erecting a channel member having flanges, in applying a second channel member of less length than the first mentioned channel member with its flanges applied to the flanges of said first channel member at the lower end thereof, pouring plastic composition between the said channel members, moving the second channel member from the poured plastic composition after it is set and securing it in place with respect to the first channel member at a greater elevation, and pouring a second section of plastic composition and progressively moving the second mentioned channel member with relation to the first channel member until the element of the building being formed is completed.

2. The herein described method of forming a structure consisting in erecting a channel member having flanges with coinciding recesses in said flanges, in which recesses reinforcing bars are seated, .in applying a second channel member of less length than the first mentioned channel member with its flanges applied to the flanges of said first channel member at the lower end thereof, with the edges of the second channel member engaging the said reinforcing bars, pouring plastic composition between the said channel members, moving the second channel member on said bars from the poured plastic composition after it is set and securing it in place with respect to the first channel member at a greater elevation, and pouring a second section of plastic composition and progressively moving the second mentioned channel member with relation to the first mentioned channel member until the element of the building being formed is completed.
